X-Band 768-Channel 2D Active Phased Array Antenna
A mission-ready cross-shaped active array intelligently optimized for superior spatial resolution and power efficiency. Delivers a commanding ≥89.5 dBm EIRP within a highly compact 65mm low-profile chassis.
Cross-Shaped Topology
Features an optimized 768-element layout (1024 array minus 4 corners). This advanced cross-shaped geometry preserves ultra-sharp beamwidths while significantly reducing parasitic power draw.
Extreme EIRP Output
Generating an EIRP of ≥ 89.5 dBm across the entire 9.2 to 9.8 GHz frequency band, ensuring highly reliable long-range target illumination under severe tactical conditions.
Precision Beamwidth
Delivers an incredibly sharp 3.4° normal beamwidth (Transmit) and an angular pointing error of ≤ 0.15° within the core tracking envelope, guaranteeing strict monopulse tracking accuracy.
Protocol Transparency
Fully documented Synchronous RS422 protocol allowing baseband engineers absolute control over internal phase shifters and real-time operational telemetry (current, temp, fan speeds).
X-Band 768-Channel Active Phased Array
TOPOLOGY: CROSS-SHAPED (1024 - 4 CORNERS)This high-performance system consists of 768 active antenna elements intelligently distributed across a specialized cross-shaped Antenna-in-Package (AiP) matrix. The architecture integrates a monopulse sum-and-difference network, power supply wave controller, and frequency synthesizer into a highly compact 65mm-thick chassis. By actively removing the corner elements of a traditional 1024-grid, this array minimizes redundant power consumption while preserving the central aperture's precision beamforming capabilities.
This panel hits the exact power-to-performance sweet spot for mobile radar systems. It achieves a commanding ≥ 89.5 dBm EIRP and an extremely sharp 3.4° spatial beam, yet strictly limits maximum power consumption to ≤ 800W at a 20% duty cycle. Total mass is kept under 14 kg. The exposed synchronous RS422 protocol structure offers radar architects unparalleled backend control for deep hardware integration.
